On-Line Monitoring of Water in Acetic Acid with a ClearView® db Photometer
1 PagesPurpose: To determine water content in acetic acid with sample temperature correc- tion. Approach: A full spectrum NIR spectrome- ter was used to measure the spectra of 0-15% water in acetic acid at various temperatures in a 5 mm cuvette cell. Results: The resulting spectra are shown in Figure 1. Minimum temperature sensitivity is found at 1420 nm. (vertical line). Excellent linearity is achieved (see Figure 2) in the range tested, up to 1
